Followup #35679 and #24556 # Background Previously, the cloud logs were written to files. The main cloud logs include meta_service.INFO and meta_service.WARNING, doris_cloud.out. In a K8s deployment environment, logs usually must be output to standard output, and other components process the log stream. # Solution This PR made the following changes: Modified the glog config: - When started with --daemon, logs are still written to various files, and the format remains unchanged. - When started with --console, meta_service.INFO's log is output to standard output and marked with the prefix RuntimeLogger. Examples are as follows: ``` RuntimeLogger I20240605 23:41:20.426553 4137369 runtime_query_statistics_mgr.cpp:245] Report profile thread stopped ``` Added a new cloud config: `enable_file_logger`, which defaults to true. This indicates that logs will be recorded in files regardless of the startup method. For example, if it is started with `--console`, the log will be output to both the file and the standard output. If it is false, the log will not be recorded in the file regardless of the startup method.

Background
Previously, the cloud logs were written to files. The main cloud logs include meta_service.INFO and meta_service.WARNING, doris_cloud.out.
In a K8s deployment environment, logs usually must be output to standard output, and other components process the log stream.
Solution
This PR made the following changes:
Modified the glog config:
When started with --daemon, logs are still written to various files, and the format remains unchanged.
When started with --console, meta_service.INFO's log is output to standard output and marked with the prefix RuntimeLogger.
Examples are as follows:
Added a new cloud config:
enable_file_logger, which defaults to true. This indicates that logs will be recorded in files regardless of the startup method. For example, if it is started with--console, the log will be output to both the file and the standard output. If it is false, the log will not be recorded in the file regardless of the startup method.
